About Yamaha

Country of Origin: Japan
Founder: Nippon Gakki (Genichi Kawakami led motorcycle entry)
Best Known For: R-series sportbikes, MT nakeds, YZ/WR off-road, Ténéré ADV

Company History

Yamaha blends engineering polish with musical-instrument attention to feel. From the RD two-strokes to modern crossplane R1s, its sportbikes emphasize chassis communication and reliability. Off-road, YZ/WR platforms define durability and race-fed development, while Ténéré ADV models offer long-legged, serviceable travel. Global dealer depth, parts commonality, and conservative updates make Yamahas easy to own and hard to break. The brand’s hallmark is balance: machines that work on Monday, thrill on Sunday, and keep their manners for decades.
